ably of dimensions corresponding to those of a conventional window frame used in houses and :other buildings for admitting light and air. If so desired it may be of Isuchsize that it may be fitted into a conventional window frame after the usual'sasheshave been removed: therefrom.

Y The-supper section of the outer sashis-rhingedly mounted by; hi11ges19 .at..one. sidefor swing-ingy movement from the-closed positiontshow-n to "an. opened; position ..;in.- which 11; extends outwardly. from; the. frame l and the-lower: section: of the outer sashv has its; upper end ;connected with the lower end" of: the upper section by; hingesi min or.-

derthat .it maybe swung-outwardly and-upwardly to an; opened; position. Suitable f astene rs-,,. such. a as: the: latches- H and [-2, v may be provided; for;

holding; thetwosectionssof the outer sash closed but permittinggthem .-'to be: opened-when lpushed outwardly; by, ai-ipersom in. acroom-(withwhich the window communicates.

Thexinner sash; has itsr twohseetions. free-fram eachaotherzand :provided. at: thei-rgsides with rings:

l3 and M in order that a person may engage his fingers through the rings and individually withdraw the panels of sections from the frame. The upper section 5 carries fastener members I5 adjacent its side edges which are spaced from each other longitudinally of the sash section, and from an inspection of Figure 3 it will be seen that when this upper section is thrust into the seat or channel 3 of the frame I the fastener members will engage between the jaws l6 of the companion fastener members I! which are'mounted against the spacing strips 2 and releasably hold the upper sash section in place. The lower sash section 5 is also provided with latches at its opposite side edges which may be spring latches [8 formed as shown in Figure 5. Each of these latches has a casing H! which is embedded in the frame of the lower section and houses a spring 2%] by means of which a plunger 2l is urged outwardly for engagingln a companion socket 22 carried by the frame I. Since the two sections of the inner sash are free from each other either may be removed without disturbing the other. The panes of glass may then be cleaned and the sash sections replaced by a person within the room. By lifting the outer sash from its hinges it. may also be moved into a room for cleaning of its glass panes and then replaced.

In order that the lower section 6 of the outer sash may be opened without disturbing the screen the screen is formed midway the width of its lower end with a passage 23 for passage of an actuating rod or handle 24 through the screen. This rod has its forward end portion 24 pivotally mounted and terminating in a pin 25 which fits into a socket 26 formed in the lower end of the lower section 6' of the outer sash. When the lowersection of the outer sash is closed the handle or rod 24 may be swung to a'folded position in which it IS disposed along the inner surface of the lower end of the screen where it will be out of the Way and aid in holding the lower section of the outer sash closed.

Having thus described the invention, what is claimed is: i

1. In a window structure, a'frame formed along its sides and across/its top with inturned recesses constituting inner and outer seats, lower portions of the outer seats having inwardly offset portions constituting auxiliary seats, inner and outer main and auxiliary sashes fitted into said frame and engaged in'the inner and'outer seats, the auxiliary sashes being under the main sashes, the outer auxiliary sash being hinged to the outer main sash, a screen in said frame engaged in the auxiliary seat, the outer auxiliary sash and the lower portion of the outer main sash bearingagainst the outer face of said screen, and fasteners for releasably holding the sashes in place. 1

2. In a window structure, a frame formed along its sides and across its top with inturned recesses constituting inner and outer seats, lower' portions of the outer seats having inwardlyoffset portions.

constituting auxiliary seats, inner and outer main and auxiliary sashes fitted into said frame and engaged in the inner and outer seats with the constituting inner and outer seats, lower portions of the outer seats having inwardly offset portions constituting auxiliary seats, inner and outer main and auxiliary sashes fitted into said frame and engaged in the inner and outer seats with the auxiliary sashes under the main sashes, the outer main sash being hinged at one side to the frame for swinging movement to closed and opened positions, the outer auxiliary sash being hinged along its top to the lower end of the outer main sash for swinging movement to opened and closed positions and a screen in said frame engaged in the auxiliary seat and held therein by the outer auxiliaryIsash, said screen having a passage intermediate the width of the lower end, and arod for swinging the outer, auxiliary sash outwardly and upwardly to an opened position passing through said passage and having its outer end engaged with the lower end of the outer auxiliary sash.

5. In a window structure, a frame formed along its sides and across its top with inturned recesses constituting inner and outer seats, lower portions of the outer seats having inwardly offset portions constituting auxiliary seats, inner and outer main and auxiliary sashes fitted into said frame and engaged in the inner and outer seats with the auxiliary sashes under the main sashes, the outer main sash being hinged at one side to the frame for swinging movement to closed and opened positions, the outer auxiliary sash being hinged along its top to the lower end of the outer main sash for swinging movement to opened and closed positions and a screen in said frame engaged in 45 the auxiliary seat and held therein by the outer auxiliary sash, said screen having a passage intermediate the width of its lower end, and a rod for swinging the outer auxiliary sash outwardly and upwardly to an opened position passing through said passage and having its outer end engaged with the lower end of the outer auxiliary sash, said rod having" a joint inwardly of the screen whereby the rod may be folded against the screen and extend transversely of the screen between the screen and the inner auxiliary sash.
